The amount of light that is produced by a lamp is called lumens and the more lumens the lamp has the brighter it will be. Lumens work in conjunction with kelvins and should not be taken in isolation of each other, for example if you had a very warm white lamp at 2,700 kelvins and it produced 300 lumens and you then had another lamp which was a cool white 6,000 kelvins which also produced 300 lumens the cooler lamp colour would always appear brighter to the naked eye than the warmer one this is due to the receptors in the eye that react better to a white light spectrum. Another factor on how bright a light may appear is contrast so if you shine a white 6,000 kelvin light on to a dark wall and a warm 2,700 kelvin lamp on to a white wall the warmer lamp would appear brighter due to the contrast of the material it is focused on. So when choosing a lamp always take in to account the area you want to illuminate and think about Kelvins ( colour ), Lumens ( brightness) and contrast ( colour of area )
Care should be taken for the environment and local wildlife to maintain the ecological balance. Insects, bats, wildlife can
all be effected by light pollution. The warmer colour spectrum of ( 2,700 Kelvins ) does not interfere
with insects and general wildlife as much as the blue colour spectrum of light around 6,000 kelvins which can disrupt
their normal night time activity. This also applies to bats where a anti glare light fittings works better as well as
reducing the overall light pollution in the area. You must also be mindful of your neighbours and the effect your lighting
can have on them and shining a 500w tungsten halogen flood light in to their windows at night will cause them distress.
Try to keep the light in a downward position and local to the items you want to illuminate and even if you want to illuminate
tall trees it can be done in a sympathetic way by placing a ground buried or surface spike flood light directly under
the trees to illuminate the canopy. Some light fittings also have a anti glare shield fitted to reduce light pollution.
